You ca n place y our Broadband Router on a desk or other flat surface, or you ca n mount
it on a wall. For optimal performance, place your Broadband Router in the center of your
office (or your home) in a location that is away from any potential source of interference,
such as a metal wall or microwave oven. This location must be close to power and network
connection.

2.2.2 Setup LAN connection

a. Wired LAN connection: connects an Et hernet cable from your computer’s Ethernet port

to one of the LAN ports of this product.

b. LAN connection: locate this product at a proper position to gain the best transmit

performance.

Figure 2-3 Setup of LAN and WAN connections for this product.

2.2.3 Setup WAN connection

Prepare an Ethernet cable for connecting this product to your cable/xDSL modem or

Chapter 3 Network Settings and Software
Installation

To use this product correctly, you have to properly configure the network settings of your
computers and install the attached setup program into your MS Windows platform (Windows
95/98/NT/2000).

3.1 Make Correct Network Settings of Your Computer

The default IP address of this product is 192.168.123.254, and the default subnet mask is

255.255.255.0. These addresses can be changed on your need, but the default values are
used in this manual. If the TCP/IP en vironment of your computer has not yet been configured,
you can refer to Appendix A to configure it. For example,

1. configure IP as 192.168.123.1, subnet mask as 255.255.255.0 and gateway as

192.168.123.254, or more easier,

2. configure your computers to load TCP/IP setting automatically, that is, via DHCP
server of this product.

After installing the TCP/IP communication protocol, you can use the ping command to check
if your computer has successfully connected to this product. The following example shows
the ping procedure for Windows 95 platforms. First, execute the ping command

ping 192.168.123.254

If the following messages appear:

Pinging 192.168.123.254 with 32 bytes of data:
Reply from 192.168.123.254: bytes=32 time=2 ms TTL= 64

a communication link between your computer and this product has been successfully
established. Otherwise, if you get the following messages,

Pinging 192.168.123.254 with 32 bytes of data:
Request timed out.

There must be something wrong in your installation procedure. You have to check the
following items in sequence:

1. Is the Ethernet cable correctly connected between this product and your computer?

13

Tip: The LAN LED of this product and the link LED of network card on your computer
must be lighted.

2. Is the TCP/IP environment of your computers properly configured?
Tip: If the IP address of this product is 192.168.123.254, the IP address of your

computer must be 192.168.123.X and default gateway must be 192.168.123.254.
